SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 438,956, dated October21, 1890.

Application filed January 6, 1890. Serial No. 336,036. (No model.)

T a/ZZ whom t may concern:

Be it known that I, GARY B. SMITH, a citizen of the United States ofAmerica, residing at Kansas City, in the county of Jackson and State ofMissouri,have invented new and usefnl Improvements in SpringBed-Bottoms. of which the following is a specication.

My invention has relation toimprovements in spring bed-bottoms, and theobject is to 1o provide a cheaply-constructed and durable bed-bottomhaving an easy and comfortable springing function.

Vtith this Object in View my invention consists in the novelconstruction of parts and their combinations, as willbe hereinafterInore fully described, and specially as the same is particularly pointedout in the claims.

I have fully and clearly illustrated my inyention in the accompanyingdrawings, wherezo 1n- Figure l is a plan view of my improved bedbottomarranged in a bedstead,showing, also, a means for stretching andtightening the bottom. Fig. 2 is a detail view of the tightening means.Fig. 3 is a plan view of a modi- Iied construction wherein the strandcomprising the bottom consists of a single wire or cord.

A designates the bedstead, which is of any of the usual constructionshavingcorner-posts.

B B designate supporting-chains arranged at each end ot' the bed-bottomand adapted to have their ends connected to supports at the corners.Each of these chains is of a length greater than the distance betweenthe sup- 3 5 ports l, by which they are connected with the bed-posts, sothat when they are drawn taut by the strands of the bottom they assumethe angular or V-shaped positions between the bed-posts, as shown inFigs. l and 3. To the 4o middle of one of the supporting-chains issecured one end of a strand 2 of which the bottom is composed. Thisstrand is carried through the middle link of the supportingchain at theother end of the bed-bottom, then back to and through a link of thechain at the other end ofthe bed-bottom, thence across to and through anopposite link in the same chain beyond the center strand, and thenceback to the other supporting-chain, and the strand thus laid andinterwoven or connected to the respective chains, with each successiveend and side line or straight portion of the strand arranged nearer tothe outer sides and ends of the bed-bottom until the requisite number isreached and the size desired attained. The bottom is thus composed of asingle continuous strand carried through the links of the supporting endchains and arranged in the form of substantially rectangularconvolutions or coils, each convolution being supported at its cornersby the end chains, substantially as shown. The ends of the strand arethen secured to one of the chains, as may be seen at 3 in the drawings.

I prefer to use for the strands a metal coilspring, as shown in Fig. Iof the drawings, as this gives to the bed-bottom an easy and pleasantresiliency; but for a bed-bottom not accompanied with so much resiliencythe continuous strand may be a single straight wire or rope, as shown inFig. 3 ofthe drawings.

In case it is desired,the bottom maybe supported on a rectangular frameil, as shown.

To stretch the bottom when arranged in a bedstead, bearings 5 6 aresecured in one ot' the posts, and in these is arranged a verticalsliding rod 7, having a strand wound thereon and leading to the end ofthe chain connected thereto, and on the upper bearing is secured aclutch-piece 8. On the upper end ot' the rod is secured a clutch 9,above which the end of the rod projects, as l0, and is formed to take awrench, by which the rod and clutch may be turned and the bed-bottomtightened to suit. y

Having thus described my invention so as to distinguish it from otherdevices existingv in the art, I proceed to particularly point out,

and distinctly claim the parts, improvements, and combinations.

I claim as my invention as follows:

1. The bed-bottom herein described,com posed of the end chains of alength greater than the distance between the supports to which theirends are connected and abottom consisting of a single continuous strandconnecting the middle of said supporting end chains and arranged in theform of substantially rectangular convolutions or coils, sucheonvolutions being supported at their corners by the said chains,substantially as described.

2. The bed-bottom herein described, composed of the end chains and abottom consisting of a single continuous strand of coiled Spring metalconnecting the middle of the said supporting end chains and arranged inthe form of substantially rectangular convo- :o lutions or coils, suchconvolutions being supported et their corners by the said chains,substantially as described.

In Witness whereof I have hereunto set my hand in the presence of twoattesiing wit;- nesses.

GARY B. SMITH.
